嗜中性球低下（Neutropenia）個案因免疫防禦機制受損，極易發生伺機性感染，因此護理重點在於「保護性隔離（Protective Isolation / Neutropenic Precautions）」。正確措施包括落實手部衛生以阻斷傳播鏈、移除潛在病原體來源（如花卉土壤中的綠膿桿菌）、限制訪客以減少交叉感染風險，以及定時監測體溫以利早期發現感染跡象。臨床思路應優先考量感染預防，任何可能接觸病原體的行為均須嚴格禁止。
Patients with neutropenia have impaired immune defenses and are highly susceptible to opportunistic infections, so the focus of care is protective isolation (neutropenic precautions). Correct measures include practicing hand hygiene to break the chain of transmission, removing potential sources of pathogens (such as Pseudomonas in the soil of cut flowers), restricting visitors to reduce cross-infection risk, and regular temperature monitoring to permit early detection of infection. Clinical reasoning should prioritize infection prevention, and any behavior that could expose the patient to pathogens must be strictly prohibited.
美國醫院對於嗜中性球低下（通常 ANC < 500/mm³）的規範極為嚴格，病房內通常禁止任何生食（包含沙拉、生魚片），甚至嚴格執行負壓或正壓隔離病房政策，與台灣臨床對於「低危險群」的寬鬆程度可能略有不同。
